How to convert square meters to square kilometers
Area factors are squared length factors: 1 ft² = (0.3048 m)². The acre here uses international feet; historic US survey acres differ slightly.
km² = m² ÷ 1000000One square kilometer corresponds to 1000000 square meters, so divide by that figure. Displayed constants may be rounded; the converter uses the stored factor before rounding the result.
0.00001 km² = 10 ÷ 1000000Square meters to square kilometers conversion table

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
